The spring of a spring balance is 5.0in. long when there is no weight on the balance, and it is 8.4in. long with 4.0 lb hung from the balance. How much work is done in stretching it from 5.0in. to a length of 12.8in.?
Answer: work is done in stretching it from 5.0in. to a length of 12.8in is 36 lb.In
Step-by-step explanation:
We know that
f(x) = kx
given that;
Natural length L = 5
x = 8.4 - 5 = 3.4
force F = 4.0 lb
f(x) = kx
we substitute
4 = k × 3.4
k = 4 / 3.4
k = 1.1764 = 20/17
Now work done from natural length to 12.8
x = 12.8 - 5 = 7.8
work done = ₀∫^7.8 f(x) dx
= ₀∫^7.8 kx dx
we substitute value of k
= ₀∫^7.8 (20/17)x dx
= 20/17 [ x²/2 ]
= 20/17 [ (7.8)²/2 - 0 ]
= 1.1764 × 30.42
= 35.786 ≈ 36 lb.In
Therefore work is done in stretching it from 5.0in. to a length of 12.8in is 36 lb.In

As part of a class project, a university student surveyed the students in the cafeteria lunch line to look for a relationship between eye color and hair color among students. The table below contains the results of the survey.
From the sample population of students with blond hair, what is the approximate value of the relative frequency of students with green eyes?
The required approximate value of the relative frequency of students with green eyes is 0.27. Option A is correct.
What is Statistic?Statistics is the study of mathematics that deals with relations between comprehensive data.
Here,
The population of the student having blond hair = 78
Total number of students with blond hair and green eyes = 21
Now,
Approximate value of the relative frequency of students with green eyes,
= 21 / 78
= 0.27
Thus, the required approximate value of the relative frequency of students with green eyes is 0.27. Option A is correct.

The dispersion among sample means is less than the dispersion among the sampled items themselves becausea:______
a. Each sample is smaller than population
b. Very large value are averaged down
c. Sampled items are all drawn from the same population
d. None of thesee.
e. b and c
Answer:
The dispersion among sample means is less than the dispersion among the sampled items themselves because:______
b. Very large values are averaged down
Step-by-step explanation:
The sample means represent average values obtained from both large and moderate values. Through the process of averaging, the data values obtained as the sample means are much closer to the true values. This is why the dispersions among the sampled items will be larger than the dispersions among the sample means. Sample dispersions describe how spread out the data values are on the number line.

82%There are 24 students in a class.
8 of the students are boys.
b)
a)
Write the amount of boys in the class as a fraction in its simplest form.
b)
Write the amount of girls in the class as a fraction in its simplest form.
Answer:
Boys: 1/3
Girls: 2/3
Step-by-step explanation:
There are 8 boys in the class out of 24 students.
The fraction will be 8/24. Both the numerator and the denominator are divisible by 8.
8 ÷ 8 = 1
24 ÷ 8 = 3
The simplest form will be 1/3.
There are 16 girls in the class because 24 - 8 = 16.
The fraction will be 16/24. Both numbers are divisible by 8.
16 ÷ 8 = 2
24 ÷ 8 = 3
The simplest form will be 2/3.
Hope that helps.

The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and value of x, the cost of each cavity filling?
4 x + 89.95 = 628.35; x = 134 dollars and 60 cents
4 (89.95) + x = 628.35; x = 268 dollars and 55 cents
4 x + 89.95 = 628.35; x = 179 dollars and 58 cents
4 (89.95) + x = 628.35; x = 538 dollars and 40 cents

Admission to the local amusement park cost $5.25 and each ride cost $2.50 which of the following equations represents the cost C in dollars for admission to the park with ex ride tickets?
Answer:
C=2.50r+5.25
Step-by-step explanation:
(r represents each ride cost)
5.25 would be the y-intercept since that's the initial fee to enter the park, and 2.50 would be the slope since each ride would cost that much.

because in y intercept we take x=0
so put x=0 in the given equation
then solve it
f(x) = 2+4(0)+3
f(x) =2+3
f(x) = 5
